Moved the DSAT only TV/PVR yesterday. Three coax's from the dish to
the kit. All three worked before the move, one now doesn't. B-(

There is a joint (F-type plugs and a coupler) in each coax outside
that had been kept dry and ventilated in plastic bag open at the
bottom. On inspection there was no sign of damp/corrsion etc in the
joins. These joints are now exposed but wrapped in self amalgamting
tape to keep the weather out.

How can I identify which is the cable that isn't working at the
joins, without removing the SAT wrapping?

It is not really practical to chase out from the bundle the duff
cable back to the joints. I've tried a "tone thrower" as one would
use on telephone/network cabling but that doesn't get 15' from the
end of the cable.
